Every day, hundreds of thousands of scholars study human behavior. Every day, a few of their studies are bundled and distributed via e-mail by Kevin Lewis, who covers the social sciences for The Boston Globe and National Affairs. And every day, I file away these studies because I find them bizarrely interesting.
In this column, I’m going to try to summarize as many of these studies as space allows. No single study is dispositive, but I hope these summaries can spark some conversations:
Female mammals tend to avoid close male relatives during moments of peak fertility in order to avoid inbreeding. For the journal Psychological Science, Debra Lieberman, Elizabeth Pillsworth and Martie Haselton tracked young women’s cellphone calls. They found that these women had fewer and shorter calls with their fathers during peak fertility days, but not with female relatives.
Classic research has suggested that the more people doubt their own beliefs the more, paradoxically, they are inclined to proselytize in favor of them. David Gal and Derek Rucker published a study in Psychological Science in which they presented some research subjects with evidence that undermined their core convictions. The subjects who were forced to confront the counterevidence went on to more forcefully advocate their original beliefs, thus confirming the earlier findings.
